Attempts to increase the growth rhythm of juvenile Northern pike (Esox lucius, L.) by adding enzyme based ingredients into dry feed
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2013, Vol 6, Issue 2
Abstract
Northern pike’s rearing in recirculation systems is limited because of increasing FCR together with size of fish. The reason is apparently connected to the disability of pike to secrete sufficient digestive enzymes to process any offered dry feed. During feeding on natural food, the pike gets the necessary enzymes from the prey’s body. This is the reason why we added to feeds digestive enzymes and even “fish juice”. We used commercially available enzymes such as ®Colebil and ®Triferment in different dozes. We also used supplements of live feed. The results are encouraging since we noticed a higher growth rate in feeding the pikes fingerlings with dry feed enriched with protease enzymes.
